The bereaved mother is also seen with Charlotte Beaumont, who plays her 15-year-old daughter Chloe, in the cemetery, fuelling rumours that the exhumation of a grave could be the focus of series two.

Beth was the mother of murdered eleven-year-old Danny and her suspicions grew throughout the series about who she could and couldn't trust.

Fans were taken on a wild rollercoaster ride as she became increasingly suspicious of her husband, Mark.

While Beth believed that Mark, played by Andrew Buchan, had murdered her son after he couldn't provide an alibi, the killer later transpired to be Detective Sergeant Ellie Miller's husband, Joe, played by Matthew Gravelle.

Throughout series one of the hit show, Beth was three months pregnant, and is seen looking considerably bigger as filming for the second series begins.

While the storyline has been kept secret, ITV bosses have previously revealed that there will be surprises in store for the show’s second series.

Will Mellor, who played psychic phone engineer Steve Connolly in the first series, has even suggested that the new series may not feature a whodunnit.

He said: ‘I can’t see it being about another murder because it will be a bit too coincidental. All I know is it’s going to be a surprise because the writer always catches you out,’ he said. ‘Whatever it’ll be, it’ll be fantastic.’

New faces are also set to join the cast, including Marianne Jean-Baptiste, James D’Arcy, Eve Myles, Phoebe Waller-Bridge and Charlotte Rampling, but no details of their characters have yet been revealed.
